Hello Mozilla Community, I am looking for a free Firefox extension that can help me view the mobile layout of my website and identify errors to speed up the site. Additionally, I need an extension or tool that can help find and fix bugs on my WordPress site to enhance performance in the Firefox browser. My website is [this site](https://topfollowapkguru.com), where I provide download links for my app. Ensuring the site loads quickly and is free of errors is crucial for providing a good user experience. Could anyone recommend such extensions or tools available for Firefox? Any guidance or suggestions would be greatly appreciated! Thank you for your help! Best regards, Durrani Zeeshan
